A simple oozie [ cloudera 5.2 ] SSH action takes 10 minutes to execute or times out, though succeeds eventaully ..... Why

We have a sood size oozie server [ where the shh action executes from ] and a giant target linux box [ where the ssh action is remotely executed ], yet the time to execute takes nearly 10 minutes....the result is succesful ....eventually .  Is this normal?

  <action name="remote-1">

    <ssh xmlns="uri:oozie:ssh-action:0.1">

    <host>${user}@${host}</host>

    <command>ls -l</command>

    <capture-output/>

  </ssh>

  <ok to="check-stage-2-return"/>

  <error to="kill"/>

  </action>
